Screw action grips provide a very simple and effective method for holding test specimens in a wide range of applications. The dual-action design of 2710-200 series grips means that jaw faces can be independently adjusted to accommodate different specimen thicknesses and geometries, ensuring that the line of tensile force remains concentric with the grip body. They can be equipped with a selection of optional jaw faces with a choice of surfaces including smoothground, rubber-coated, serrated and wave profile.
